One simple method of whitening teeth is to use teeth bleaching trays. These trays can be custom made or standard ones.
The custom made trays are fitted in two steps. To ensure getting good results, it’s best to use good quality teeth whitening kits which would be a little more expensive. However, the price would include a high quality whitening gel along with a well fitting tooth tray.
Custom teeth trays are comfortable since they’re moulded for your teeth and mouth shape. The trays are made using a very soft material which fits well and keeps the whitening gel in constant contact with the teeth for the most effective results. This is the most important part of the whitening process no matter what technique you use.
Standard trays use thermo form trays. While these trays do get the whitening done they aren’t really comfortable to wear especially for long hours or overnight. However if you have a limited budget then thermo form trays are a good option. Sometimes these trays may need to be trimmed with a pair of scissors to get a better fit.
Whatever type of tray you use, consult your dentist for the right way to do so. Using a teeth whitening tray once a month should help you keep your teeth looking good, though results may not be as effective if you are a smoker or coffee drinker.
